The Program in C that uses a function power that calculates the power of a given number is given below:
Enter the base number: 7
Enter the exponent: 9
7.000000 raised to the power of 9 is: 40353607.000000
#include <stdio.h>
double power(double base, int exponent) {
double result = 1;
for (int i = 0; i < exponent; i++) {
result *= base;
}
return result;
}
int main() {
double base;
int exponent;
printf("Enter the base number: ");
scanf("%lf", &base);
printf("Enter the exponent: ");
scanf("%d", &exponent);
printf("%lf raised to the power of %d is: %lf\n", base, exponent, power(base, exponent));
return 0;
}
Output:
Enter the base number: 7
Enter the exponent: 9
7.000000 raised to the power of 9 is: 40353607.000000
Pro-Tips💡
In this program, the power() function takes two arguments: a base number and an exponent.
It uses a for loop to calculate the power by iterating from 0 to the given exponent, multiplying the base number with the result each time.
In the main function, the program prompts the user to enter a base number and an exponent and then passes these values to the power() function.
The function returns the power of the given number, and the program prints the result on the screen.
Please note that if the exponent is negative, the result would be a fraction, in that case you need to include the math.h library and use pow() function which handles negative exponents and floating point bases.
